RAZOR-STROPPER. 1

Specification of Letters Patent.

Application filed September 26,1913. Serial No. 792,001.

- Litchfield, in the county of ll/lontgomery and tive detail of the rocking member.

State of Illinois, have invented certain new and useful Improvements in Razor-Stroppers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is a razor stropper, of that type wherein the blade is held within aclip .which is automatically moved to and fro bytension on the strop as the latter is moved in one direction or the other, and the object of the invention is to improve a stropper of this kind.

This object is carried out by constructing the device as hereinafter more fully described and claimed, and as shown in the drawings 'wherein- Figure 1 is a central vertical sectional view through this device in use, and Fig. 2 is an end elevation thereof. Fig. 3 is a cross section taken at right angles to the section line of Fig.1. Fig. 4c is a perspective de tail of the razor clip. Fig. 5 is a perspec- Figs. 6, 7, and 8 are plan views of blanks as will be referred to hereinafter.

The first member of this device is a-main frame formed in two parts, stamped fromend being provided with tangs 2; the second side is cut out so as to form three bars 3, 4:,

and 5 extending across the bottom of the frame, and the intermediate bar has upturned lips 6 pierced with openings 7 for a purpose to appear; and the third side 8 has a large hole 9 through its center and atits upper end a pair of tangs which I have numbered 2 because they are likethose on the first panel or side. The other part of the frame is a top plate 10 whose ends are turned downward in lips 11 which overlie the upper ends of the side panels and are piercedwith eyes through which said tangs are passed,

after which the tangs are bent over to hold the frame-parts together. This top-plate also has two upstruck tongues 13 pierced with registering holes 1 1 to receive a hook H by which the entire stropper may be held while the hook is seated in some object not necessary to illustrate. Within the frame as thus constructed is the second or rocking member,

also by preference stamped from sheet metal, and the blank from which this memher is made is best seen in Fig. 8. It also is of U-shape, but inverted, its head or body portion, 20 underlying the top plate of the main frame and having lips 22 turned downward along its sides for a purpose to appear. The ends of this part are bent down- ;ward into armswhereof that numbered 23 lies inside the solid panel 1 and that nums bered 2 1 lies inside the opposite panel and is provided with a large hole. registering with-thehole 9 above" described; and under the head passes a pivot rod 21 which extends .througlrthe arms .23 and 24 and the end panels 1 and 8 of the frame.

The third member is the razor clip which is by preference made of two like pieces of sheet metal 30 havingtrunnions 31 at their extremities which are joiii'naled at 31 in the lower ends of the arms 23 and 2 1, depending tongues 32 which are movably mounted between the upturned lips 6 on the central cross bar, and two upstanding lips 33 bent inward toward each other and adapted to removably hold the razor blade R; and the two pieces are held close together by means of rivets 34;. By preference l'pass a leaf spring 35 through the eyes 7 in the lips 6 and bendv its arms upward as at 36 on opposite sides of the razor clip, which latter is disposed loosely between said arms. All parts are suitably ornamented, and their proportions and exact details and construction are not essential- In use, the registering holes on the main frame are engaged'with a hook H as shown and a razor strop S is passedupward between the bars 3 and 1, then overone lip 22 and across the head 20 of the rocking member, thence down over the opposite lip 22 thereof, and finally between the remaining bars 4 and 5 of the frame, and the ends cated through the device in a manner which will be clear. The razor blade R is then passed through the registering holes in one panel of the frame and in one arm of the rocking member and inserted into the clip, where it is held between the spring lips 38. The operator then grasps the ends of the strop and reciprocates it in a manner which will be understood, and at each draft one stretch of the strop draws against its lip 22 and moves the rocking member where it is pivoted in the frame so that the lower end of the rocking member moves the trunnions of the clip, whereas the lower extremity of the clip is held between the lips 6 in the lower portion of the main frame and cannot move. The result is that the upper portion of the clip, which is where the lips 33 hold the razor R, is thrown away from the descending stretch of the strop and the edge of the razor is borne against the ascending stretch thereof so that the latter is wiped across it and the. razor is sharpened or stropped. The presence of the spring arms 36 prevents the clip from being thrown too far outward or the rocking member swung so far to one side or the other that the lower end of the clip would be disengaged from the lips 6. After this blade has been sharpened it may be removed through the large holes in the end of the device, and another blade substituted. Obviously the stropper is capable of sharpening any blade which may be passed through these holes and held within the clip, and for this purpose the size of the stropper should be such as to accommodate it to rather long blades if it is intended that such are to be treated.

What is claimed as new is:

1. In a razor stropper, the combination with a suspended frame; of a rockin member pivoted at its upper end therein and having lips at opposite sides of its pivot, a strop passing over said upper end and both lips, and a razor-clip pivotally mounted within the lower end of said rocking member and having lips at its upper end for grasping the razor, its lower end being movably engaged with the bottom of said frame.

2. In a razor stropper, the combination with a suspended frame; of a rockin member pivoted at its upper end there1n and having lips at opposite sides of its pivot, a strop passing over said upper end and both lips, a razor-clip having lips at its upper end for holding the razor-blade, a pendent tongue at its lower end, and trunnions between said lips and tongue pivoted in the rocking member, and a pair of lips upstanding from the bottom of the main frame and between which said tongue is loosely mounted.

3. In a razor stropper, the combination with a suspended frame; of a rocking member pivoted at its upper end therein and having lips at opposite sides of its pivot, a
